HACKLiNG-WEACHINE SPECIFICATION forming part of Letters Patent No. 318,750, dated May 26,1885.

Application filed February 24, 1885.

To 0/ whom, it may concern:

13c it known that I, (Jr-mamas E. KEITH, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Haekling-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain novel and useful improvementsin machines for hackling flaX,tampico, and other fibrous materials, and has for its object to provide a device of this description, simple in construction, and which shall in its operation approximate to the hand system of hackling or hatcheling now in use; and with these ends in view my invention consists in the details of construction and combinations of elements hereinafter fully set forth, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may fully understand its construction, I will proceed to describe the same in detail, referring by letters to the accompanying drawings,forming a part of this specification, and in which-- Figure 1 is an elevation of my machine,and Fig. 2 aplan view of the same; Fig. 3, aplan view of one of the clamps; Fig. 4, a partial section of the disks, showing the adjustment of the clamps; and Fig. 5, a detail elevation of the inner face of the carriage, the lever, and rack in their relative positions.

Similar letters denote like parts in all the figures of the drawings.

A is the frame or bed of the machine,which I preferably form from metal,and which has an opening, B, along each side thereof for the purpose presently explained.

In the standards 0, projecting upwardly from the frame, is journaled the shaft D,having at one end thereof the fast pulley E.

F is a wheel or disk rigidly mounted on the shaft midway between its journals. This wheel is constructed with a T-head flange, a, upon its periphery,so that there is an annular recess or groove, 2), around it upon either side and near the edge thereof. The object of this groove will be presently set forth.

G are disks secured on shaft D so as to re- (No model.)

volve therewith. They have no peripherical flanges, and their radial measurement is that of the central disk minus the width of the flange and groove of the latter.

Upon the outer faces of the disks G- are secured metal spring-plates H, having upon their free ends catches c of any ordinary con struction. I are clamps composed of two bars held together by metal straps t, encircling their ends and secured by thumb-screws or other suitable means, and adapted to hold between the two partsthereof the tampico or other fiber to be treated in the machine. They are secured on the peripheries of the disks by placing the inner ends within the grooves b of the central wheel, and the outer ends against the catches c on the outer disks, which hold them in place by reason of the resiliency of the plate-springs H. I do not wish to be limited by the construction of the clamps or means for fastening the same to the disks which I have shown and described, as this may very readily be accomplished by a variety of simple devices.

J is a carriage, mounted by means of projeet-ing flanges 6 upon the lower edges of openings B, which form tracks, upon which said carriage may travel; and K is a screw journaled in the end of the frame A and passing through a threaded opening in the end of the carriage J. By means of this arrangement the position of the latter may be regulated upon its tracks. This screw may be operated by power from belt X,as shown, to give to the carriage a steady forward motion; or it may be operated by hand, at the pleasure of the operator.

J ournaled in the upper portion of the carriage J is a drum, L, free to revolve upon its bearings, and having upon its periphery rows of radial hackle-teeth M. These do not differ from the teeth upon the ordinary hand-hatchel, except that they are shorter than the last named.

N is a strap-brake extending over one extremity of the drum L,having one end secured to the body of the carriage J by a screw or bolt, and the other to a lever, 0, whose end is fulcrumed to the carriage at P.

Upon the inner side of the carriage-frame is placed a segmental rack, Q, adapted to hold the lever O in any position desired, and consequently the strap-brake (shown in dotted lines, Fig. 1) upon the drum with any requisite tension. I i

The operation of my improvement is as follows: The clamps referred to are filled with the proper quantity of tampico or other fiber to be treated, and are then secured in place be tween the central and the side disks. The disks carrying the clamps and their contents are then revolved by means of power applied to the pulley E at a rate of speed sufficient to cause the fibers to stand out radially from the disks by reason of centrifugal force. In their revolution they strike against the drum whose teeth separate the fibers and comb out the material. At the commencement of the process the drum is left free to revolve, or with very slight tension thereon from the brake,and the carriage is placed at the outer end of its tracks. The drum is left free to revolve for the purpose of allowing it to turn readily and its teeth to release their hold upon the fiber, Where the latter is matted or tangled without injury to the teeth or tearing of the fiber. The carriage is left at the end of its track away from the disks, so that at first only the ends of the material may be operated upon. As these ends become thoroughly combed,the carriage is moved closer to the disks and the brake gradually applied to the drum until,when the latterhas approached so that the whole length of fiber in its revolution comes Within the field of the teeth, the drum is, by increased tension upon the brake, held immovable, and it then acts as a stationary comb. As before stated, the-movement of the carriage is accomplished either by hand or by power applied to the screw by belt X, and in the former case the movement toward the disks will be positive and continuous.

In my invention I do not wish to be confined to the exact details of construction shown in the drawings, as the gist of my invention rests in the broad idea of a drum or disks carrying the fiber to be treated in combination with the toothed drum mounted on a carriage and under the control of the brake, as described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In ahackling-machine, the disks bearing upon their peripheries clamps, as described, in combination with a drum having hackleteeth thereon,a movable carriage, and a brake, substantially as set forth.

2. The combination of the disks, theclamps mounted thereon, and means for rotating said disks and clamps, with the carriage, the screw for reciprocating the same, the toothed drum journaled thereon, the lever fulcrumed to the carriage, and the brake, substantially as described. r r A r 3. In a hackling-machine, the combination, with the frame or bed, the movable carriage, and the toothed drum journaled in said carriage,of a strap-brake encircling the drum,and a lever and a segmental rack for holding the same, substantially as set forth.

4. The combination of disks F G, mounted on sha t1), clamps I, carriage J ,toothed drum L, brake N, lever O, rack Q, and the screw K, all arranged as describe l,and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
